That reply was directed at a troll that I wasn't interested in feeding. I'm not sure what you're getting at with regard to people living near lakes, but I'll try to give my own argument for why this research station is important, based upon my layman's understanding of the science.
There is a need for long term longitudinal studies on environmental pollutants and how they affect freshwater ecosystems. Canada has huge freshwater reserves, and with world supplies of fresh water constantly falling, it makes sense to keep our eye on how such systems respond to external stresses, whether that be phosphates (the most commonly cited result from that station), acidification, excreted hormones, heavy metals, or otherwise. If only a single policy change comes out of such studies, leading to (for example) decreased energy and resource use for water treatment, increases in freshwater fish stocks, a greater understanding of which filter plants should be used in artificial wetlands, or (heaven forbid) a higher standard of living for communities living near such ecosystems, then I'd call it a success. Any of those could potentially lead to decreased spending in the future.
Might I be wrong? Yes, clearly! But $2 million per year is a relatively small amount, and I trust that the scientists who actually use data from this research station know what they're talking about. I'm clearly no scientist, but I think I do a pretty good job of reading sources objectively.
I'm not a blind ideologue, and I understand that budgets are limited. I just have a hard time justifying shuttering such a reputable research station while spending $140 million on commemorating the War of 1812 - that's just an example, everyone has their own target for wasteful spending. Granted your priorities may not be mine; I hope I've done at least somewhat of a decent job at "articulating why the science is needed" and why I think this is worthy of federal spending.
